Quick Radiation Reference Guide

Recommended Yearly Limit

(we get 240 to 300 millirems per year from natural background radiation)

25,000 millirems for astronaut missions

5000 millirems for adults

500 millirems for childrenA useful comparison to get an idea of reported radiation levels is the fact that the average dose that all humans on the planet get yearly from natural background radiation is 2.4 mSv per year
